Zum Inhalt springen Kangchuang Paper’s kraft paper strips and paper tapes are precision-slit narrow rolls of natural and bleached kraft paper, produced from our own master rolls and cut to any specified width — from 5mm narrow tape strips to 200mm medium-width strips — for use in automated packaging lines, furniture edge banding protection, garment care label production, void fill dispensing systems, gift wrapping rolls, and a broad range of industrial taping and binding applications. Because we manufacture the base kraft paper AND perform the slitting conversion in our Dongguan facility, we offer the full range of kraft paper grades (35gsm to 200gsm, natural brown to bleached white) in any custom width with ±0.5mm dimensional accuracy — without the distributor premium paid when sourcing custom-width strips through a packaging supply chain. Factory-direct, low minimum order, free samples shipped via DHL Express to the United States.
Automated Packaging Machines: Many packaging machines — automatic box sealers, bundle wrapping machines, produce binding equipment, and bakery packaging lines — consume narrow paper strips as binding tape or wrapping material. These machines require paper strips at specific widths (typically 10–50mm) with consistent tensile strength and roll dimensions for uninterrupted automated feeding. Off-the-shelf strip products are rarely the correct width — custom slitting is the standard solution for high-volume automated packaging operations.
Furniture Edge Protection: Furniture manufacturers and logistics providers use narrow kraft strips (typically 30–80mm wide, 80–120gsm) as edge protectors for flat-pack furniture panels during transit. The paper is applied along panel edges to prevent corner damage without the cost and plastic waste of extruded edge protector profiles. Natural brown kraft at higher gsm grades provides the stiffness and tear resistance needed for edge protection.
Garment Care Label Paper: The care label and price tag industry uses white bleached kraft strips in widths of 25–75mm as the substrate for care labels and hang tags. High brightness (80–90 GE), smooth printable surface, and consistent caliper are required for quality label production. Kangchuang white kraft strips in these widths supply label converters who die-cut individual labels from the continuous strip.
Void Fill and Cushioning Strips: Narrow kraft strips (10–30mm wide, 40–60gsm) dispensed from honeycomb paper systems or from roll dispensers provide sustainable void fill and cushioning in e-commerce packaging. The strips crumple into a cushioning mass when compressed between the product and box wall. Eco-conscious packaging operations prefer kraft paper void fill over plastic bubble wrap and foam.
Gift Wrapping and Craft Packaging: Bleached white and natural brown kraft strips in widths of 20–100mm are used by gift packaging operations, craft businesses, and e-commerce brands for decorative ribbon-like wrapping strips, product binding, and gift tape applications. The natural fiber appearance of kraft supports sustainable brand positioning.
Natural Brown Kraft (Unbleached): The standard kraft paper grade, produced from virgin wood fiber using the kraft (sulfate) pulping process. High tensile strength, natural brown color, excellent tearing and burst resistance. Available from 35gsm to 200gsm. Best for packaging, wrapping, void fill, and structural applications.
Bleached White Kraft: Treated with bleaching chemistry to remove the brown lignin color, producing a bright white paper (80–90 GE brightness). Similar strength to natural kraft but with printable white surface. Available from 35gsm to 120gsm. Best for label paper, care tag stock, gift wrapping, and food-contact packaging.
Recycled Fiber Kraft: Made from post-consumer recycled paper fiber — lower strength than virgin kraft but significantly reduced raw material cost and environmental footprint. Gray-brown color. Available from 60gsm to 150gsm. Best for void fill, protective packaging, and eco-branding applications.
PE-Coated Kraft: Natural or white kraft with polyethylene lamination on one or both sides — providing moisture resistance and heat-sealability. Used for hot-seal kraft tape, moisture-resistant wrapping strips, and food packaging strips. Available from 60gsm to 200gsm base weight with various PE coat weights.

Kraft paper strips are narrow rolls of kraft paper slit to a specified width — they are base paper without adhesive. Paper tape is kraft paper strips with pressure-sensitive, water-activated (gummed), or heat-seal adhesive applied to one face. We supply kraft paper strips (base paper without adhesive) for applications where the customer applies their own adhesive or where no adhesive is required — such as machine-bundling applications where paper is used as a mechanical wrap. For adhesive tape products, we can refer to adhesive tape converters who would apply adhesive to our base kraft strips.
Our minimum strip width is 5mm, achievable with razor blade slitting on kraft paper grades up to 80gsm. For heavier kraft grades (above 80gsm), the practical minimum strip width is 8–10mm due to mechanical stress on very narrow strips during rewinding. For specialty applications requiring strips below 5mm in width, please contact us to discuss the specific kraft grade and intended use.
For paper-bundling and tying machines: 50–70gsm provides sufficient tensile strength for most bundle-binding applications while maintaining flexibility for machine feeding. For void fill dispensing systems: 40–60gsm gives the right crumple characteristics for cushioning. For furniture edge protection strips: 80–120gsm provides the stiffness and tear resistance needed for edge protection without tearing during application.
Yes — custom printing is available on white bleached kraft strips for orders above 3,000kg. Natural brown kraft printing is available but contrast is lower than white. Print specifications should be provided in advance — we use water-based inks for kraft packaging applications. Lead time for custom-printed strip orders is 15–20 business days to allow for print setup and approval.
Natural brown (unbleached) kraft retains the lignin from the wood fiber, giving it its characteristic brown color and higher inherent tear and burst strength. Bleached white kraft undergoes a bleaching process that removes lignin for a bright white appearance — useful for printable applications and food-contact packaging — but at slightly lower strength than natural kraft of the same gsm. For packaging and void fill, natural brown is typically chosen; for label backing, care tags, and printable applications, white bleached kraft is specified.
Yes — multi-width slitting from a single master roll is a standard and cost-efficient service. For example: 50mm strips for edge protection AND 25mm strips for bundling, both from the same 80gsm natural brown kraft master roll, produced in a single slitting pass. Specify all required widths and quantities in your order inquiry and we will prepare a combined quotation.
Standard core inner diameters are 3-inch (76mm) and 6-inch (152mm) — compatible with most standard industrial dispensing equipment and paper strip applicators. Custom core inner diameters (25mm, 38mm, 50mm, 100mm) are available for equipment with non-standard core specifications. Specify your dispensing equipment’s core requirement when ordering.
Yes. PE-coated kraft paper strips (polyethylene laminated on one or both faces) are available in widths from 10mm to 200mm. PE-coated strips are used for moisture-resistant packaging tape, heat-sealable strip applications, and food-contact packaging where a moisture barrier is required. Available in natural brown or white base paper with PE coat weights from 10g/m² to 30g/m².
Tensile strength varies by paper grade and gsm. Indicative values (machine direction, MD): 35gsm natural kraft: approximately 2.0–2.5 kN/m; 60gsm natural kraft: approximately 3.5–4.0 kN/m; 80gsm natural kraft: approximately 4.5–5.5 kN/m; 120gsm natural kraft: approximately 6.0–7.5 kN/m. White bleached kraft of the same gsm is typically 10–15% lower in tensile strength. Tensile test results are available for production orders on request.
Trial orders: minimum 2 rolls per specified width — no minimum weight, shipped free via DHL Express. This gives you 2 rolls to test on your packaging equipment, check tensile strength on your machine, verify width fit in your dispensing system, and assess quality before placing production volumes. Production orders: minimum 500kg total weight.
Individual rolls are banded with stretch film for protection. Rolls are then packed in export cartons (20–50 rolls per carton depending on roll diameter and weight) with cushioning between rolls. Cartons are labeled with product grade, width, roll length, core diameter, and batch number. Container-load orders are palletized and shrink-wrapped for sea freight.
Yes. We ship kraft paper strips and paper tapes to packaging companies, label converters, furniture manufacturers, e-commerce packagers, and industrial distributors throughout the United States. Sample rolls ship via DHL Express at no cost. Production orders ship FOB Dongguan by sea freight. Contact us with your strip specification and US delivery location for a complete quotation.
